Nissens 86432 Engine Cooling Fan Clutch

The Nissens 86432 is a heavy-duty viscous fan clutch engineered for engine cooling system applications. Nissens fan clutches are designed, manufactured, and tested to OE-matching quality standards, providing reliable temperature management and long service life.

How It Works:

The fan clutch controls the engagement of the engine cooling fan by regulating the flow of a silicon-based viscous oil through an internal valve. This oil transmits engine torque to rotate the fan. Depending on cooling demand, the fan can engage partially or fully, reducing unnecessary power draw on the engine when full cooling is not required.

Key Features:

• OE-matching quality — designed and tested to original equipment specifications
• Viscous silicon oil design for smooth, progressive fan engagement and disengagement
• Stainless steel construction for durability and corrosion resistance
• Optimized fan speed modulation for improved engine performance and fuel efficiency
• Comprehensive test series including design and material improvements for long, trouble-free operation
• Drop-in replacement fitment for precise installation

Why Replace Your Fan Clutch?

A failing fan clutch can cause engine overheating at idle or in traffic, reduced climate system performance, increased fuel consumption, a drop in engine power, or grinding noises from the engine compartment. Replacing a worn fan clutch with a quality Nissens unit restores proper cooling and protects engine components from heat damage.
